• The higher the carrier frequency is, the lower the motor acoustic noise is. Unfortunately, larger
leakage current and larger noises generated by the inverter are resulted in.
• The higher the carrier frequency is, the more energy is dissipated, and the higher the temperature of
the inverter is.
• In case a mechanical resonance occurs in a system with the inverter, P.72 is helpful for improving
the performance by adjusting the values.
• The higher Carrier frequency, the inverter rated current will decline, which was to prevent the
inverter to overheat and extend the life of IGBT, so that protection measures are necessary. The
carrier frequency is 8kHz or below, rated current of a inverter is 100%, as the carrier frequency
increase, rating current will decline, and accelerate product heat to protect the inverter. Rated
current and carrier frequency relation curve shown in the following figure:
